Bu-zhong-yi-qi granule (BZYQ), a sort of Chinese herbal medicine, has exhibited therapeutic effects on ulcerative colitis (UC). However, the mechanism of BZYQ has not been fully clarified. This study was aimed at investigating the effects of BZYQ on UC rats model and at exploring its potential mechanism. Methods. The UC rats were established by enema of trinitrobenzene sulfonic acid (TNBS). The therapeutic effects of BZYQ treatment were evaluated by disease activity index (DAI), colon macroscopic damage index (CMDI) scores, and histological observation. The mRNA levels of tumor necrosis factor-\u03b1 (TNF-\u03b1), interleukin-1\u03b2 (IL-1\u03b2), and interleukin-10 (IL-10) were measured by quantitative real time-polymerase chain reaction (qPCR). The expression of tight junction (TJ) proteins, occludin and claudin-1, in the colon was determined by Western blot and immunofluorescence. The expression of toll-like receptors 4 (TLR4), nuclear factor-kappa B (NF-\u03baB), p-NF-\u03baB, myosin light chain kinase (MLCK), MLC, and p-MLC levels in colon was determined by Western blot or qPCR. Results. The results showed that BZYQ could attenuate DAI, CMDI, and histological inflammation. TJ proteins expression was decreased in UC rats, but treatment with BZYQ restored the expression of occludin and claudin-1. In addition, BZYQ administration ameliorated UC-associated increase in the production of TNF-\u03b1, IL-1\u03b2, and the expression of TLR4, NF-\u03baB, p-NF-\u03baB, MLCK, MLC, and p-MLC, while BZYQ administration increased the production of IL-10. Conclusions. The therapeutic effect of BZYQ on UC is at least partially through regulation of the secretion of some inflammatory cytokines and improvement of TJ integrity via TLR4\/NF-\u03baB\/MLCK pathway.<\/jats:p>","DOI":"10.1155\/2021\/6657141","type":"journal-article","created":{"date-parts":[[2021,3,9]],"date-time":"2021-03-09T22:05:06Z","timestamp":1615327506000},"page":"1-12","source":"Crossref","is-referenced-by-count":7,"title":["Bu-Zhong-Yi-Qi Granule Enhances Colonic Tight Junction Integrity via TLR4\/NF-\u03baB\/MLCK Signaling Pathway in Ulcerative Colitis Rats"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9556-8138","authenticated-orcid":true,"given":"Xiuhong","family":"Kang","sequence":"first","affiliation":[{"name":"Digestive Disease Center, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7784-8067","authenticated-orcid":true,"given":"Mengdi","family":"Jia","sequence":"additional","affiliation":[{"name":"Digestive Disease Center, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1986-3511","authenticated-orcid":true,"given":"Luqing","family":"Zhao","sequence":"additional","affiliation":[{"name":"Digestive Disease Center, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0457-1727","authenticated-orcid":true,"given":"Shengsheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Digestive Disease Center, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mayocp.2014.07.002"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2011.10.001"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2013.00280"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.15806\/j.issn.2311-8571.2016.0043"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1136\/gutjnl-2012-303207"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1002\/ibd.20539"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcmgh.2017.03.007"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1152\/ajpgi.1995.269.4.G467"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9440(10)61196-0"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1152\/ajpgi.2000.279.5.G875"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajpath.2017.08.005"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.174.8.4453"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1128\/iai.68.12.7010-7017.2000"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(07)60751-X"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2017.07.032"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1007\/s40262-018-0676-z"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i39.14099"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1177\/0960327115627686"},{"issue":"9","key":"19","doi-asserted-by":"crossref","DOI":"10.1142\/11254","article-title":"Effect of Buzhong Yiqi Decoction on the state of microinflammation and TLRs \/ MyD88 signaling pathway in patients with chronic nephritis","volume":"29","author":"S.
